@johnros: You have the low-power chipset (LP). You need this firmware:

sudo apt-get install firmware-b43-lpphy-installer

[WORKSdefaultITguy]

Thanks for the help. I'm so glad to have found this forum. Your help of another user near the beginning of this thread fixed my wifi issue. Thanks again, I'm looking forward to learning more as I explore Ubuntu.

[wildmanne39]

Your welcome! and welcome to the forum.

[TREESofRIGHTEOUSNESS]

I would like to add something (I searched through about 11 pages and didn't find this answer, (man dpkg helped).
If for some reason you mistakenly install the driver from jockey *after* installing b43-fwcutter and firmware-b43-installer you will be stuck in a dpkg --configure -a crash loop.
to fix this simply run

sudo dpkg -P bcmwl-kernel-source

Which purges the bcmwl-kernel-source package (installed by jockey... the Additional Drivers program) from your computer much like apt-get does....
So if someone (such as myself) ever needs to find this command here it is.

[wildmanne39]

Thanks TREESofRIGHTEOUSNESS I have never used that command before, we use this one.

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

[TREESofRIGHTEOUSNESS]

Yeah when you install the propreitary drivers through jockey (Additional Drivers) *after* installing b43 packages, it got my computer stuck saying I needed to run [CODE}sudo dpk --configure -a[/CODE] which results in a serious locked up crashed computer (everytime). So since I can run apt-get purge (remove, autoremove,etc....) I had to use dpkg. If someone really screws up by installing drivers from jockey after already installing them. I had to install windows to flash the BIOS on 2 computers and both have b43, so when reinstalling I accidentally took the "you need to install propreitary drivers" OSD bait. So after fruitless internet searches, I came across this thread, and tried your solution (which resulted in the loop of crashing). That didn't work so I looked at dpkg man pages and discovered the -P (purge) option. Voila! So for users that are stuck like that I wanted to add my findings to your page. I also deleted the "lock" file in /var/cache/apt but I don't know if that is related to fixing it. I tried everything I could think of.... having a newly installed borked OS is lame

[wildmanne39]

Yes, now I understand why you used that command.

Nothing worse then a broken system.

hi to everyone i am using Backtrackr on VmWare my Wireless network Adapter is Ralink RT3090
after command

root@bt:~# iwconfig
lo no wireless extensions.


eth1 no wireless extensions.


root@bt:~#
how to get my wifi work?
and i am tryed another command
root@bt:~# airmon-ng start wlan0




Found 1 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

Interface Chipset Driver




root@bt:~#

i have no interface chipset and driver.

[sasky84]

Hi, it looks like you installed the driver for this card in additional drivers if so please do this:

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

Then run this command and watch for errors.

sudo apt-get install b43-fwcutter firmware-b43-installer

After it intalls disconnect your wired connection and restart your computer.

This helped me also with Ubuntu 13.04 (Asus Eee). Thanks!
